I think the problem is having both enclosed polygons and lines in the
same file. Even if you did break the hill top contour (scissors/break or
pen/break), you could always re-snap the line using v.digit/v.support
-s.
[grasslist:451] suggests a cheaper option - using the MapPublisher
plugin to export directly to .shp or .e00 files.

Sujoy,
That is an interesting observation. I checked the contours in
illustrator
and I do have at least one enclosed polygon. Unfortunately, it is a
hill
top. What would be the best way to handle it. Scissor tool and make a
break maybe?
Thanks
Kurt

When using AI for digitizing contours, I noticed that the .dxf export
file could not be read in GRASS if the contours were represented as
complete polygons (or closed lines). Now I just make sure that every
entity in the AI .dxf is a (open) line feature and the import seem to
work fine.Sujoy Chaudhuri

Hi Folks,
BTW, thanks for those who helped with my last problem. I couldn't
remember
the file name.New challenge, and some of you will remember trying to help me with
this
some months ago. I put it aside then because I had other things to
do.
No
I am back. I have contour lines I've drawn in Adobe Illustrator. I
want to
move them into GRASS as vectors so I can label the elevations and
start
using them. This seems to elude me.
I tried converting them into .dxf files, but GRASS can't seem to see
it.
I've tried using Textwrangler to change the line breaks to UNIX. I've
even
used the program Linebreak for this purpose. I also tried using
Textwrangler to do a hexdump and converted the file to ascii.One thing I am considering is printing out the contours and trying to
use
v.digit to trace them. Can I do this with out a digitizing tablet
using
an
optical mouse? I may have to get some transparent film and make a
target to
tape on it.Can anyone thing of an easier way of doing it.
Any help or advice will be greatly appreciated.
Thanks.
Kurt
